PRODUCT DETAILS

Duplex 2205 stainless steel plate for extreme environments

Daxun offers a large stock of 2205 Duplex Stainless Steel Plates in sizes from 1/16 inch (1.0mm) to 6 inches (152.4mm) thick. The yield strength of this material is about twice as high as that of regular austenitic stainless steels, which means designers can use less material and save on costs compared to using 316L or 317L stainless steel.

2205 Duplex Stainless Steel is made up of 22% chromium, 3% molybdenum, and 5-6% nickel. It is strong and has great resistance to problems like stress corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion, even in tough environments, thanks to its superior corrosion resistance. This type of stainless steel is popular because it combines the best properties of both ferritic and austenitic steels.

Grade 2205 standards have improved over the years, making it a reliable and versatile material. It has great resistance to corrosion, including in seawater, can be welded using common methods, and is highly resistant to heat. If you need more details or pricing, contact Daxun.

Duplex 2205 Stainless Steel sheet and plate

Duplex SS 2205 is a very useful type of stainless steel that combines two structures: ferritic and austenitic. It has 22% chromium, 3% molybdenum, and 5-6% nickel, which makes it strong and highly resistant to different kinds of corrosion, like pitting, crevice, and stress corrosion. It can handle tough conditions and is often used in harsh environments.

Packaging details for Duplex SS 2205 include the use of durable materials to ensure the product’s integrity during shipment, specific shipping marks for easy identification, and timely delivery schedules.

2205 plate features

  • Increased corrosion resistance against crevice, pitting and stress corrosion cracking
  • In terms of energy absorption: high resistance to erosion and abrasion over a wide temperature range
  • Unique strength, surpassing that value of other chromium-nickel stainless
  • Combined properties of ferritic and austenitic steels, which by their very nature have high mechanical strength and excellent toughness
  • Excellent impact strength properties
  • Higher formability compared to other chromium-nickel steels
  • Excellent weldability, also possible on larger cross sections
  • Can be used in temperatures up to 300°C

Stainless Steel 2205 Applications

  • Chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers
  • Oil and gas exploration and processing equipment – piping, tubing, and heat exchangers
  • Marine and other high chloride environments
  • Effluent scrubbing systems
  • Pulp and paper industry – digesters, bleaching equipment, and stock-handling systems
  • Cargo tanks for ships and trucks
  • Food processing equipment
  • Biofuels plants

Quality, delivery, inspection

  • Daxun strictly controls product quality. Before placing an order, we will send you the product warranty, or if you need samples for testing, we can also send samples for free.
  • During the production process, we measure the diameter, thickness, and surface of the product. Our delivery time is strictly in accordance with the contract.
  • Support customer third-party agencies to go to the factory for inspection
  • Support free samples to customers for testing
  • Support on-site or video factory inspection
  • Identification labels are used to ensure quality control and accurate product tracking, adhering to standard specifications or customer’s instructions.

PROCESSING

Machining Duplex 2205 is a bit more challenging compared to 300 series austenitic stainless steels. It requires higher cutting forces and tends to wear tools more quickly. Here are some guidelines for machining:
A) Use powerful, rigid machines with strong, stable mounting for both tools and the workpiece.
B) Minimize vibration by keeping the tool extension as short as possible.
C) Use the appropriate cutting tools and speeds to manage wear and maintain quality.
